All the latest BIOS updates and drivers are used during testing. We perform generally under real world conditions, meaning KitGuru tests games across five closely matched runs and then average out the results to get an accurate median figure. If we use scripted benchmarks, they are mentioned on the relevant page.
Some game descriptions are edited from Wikipedia.
those cards are pure sex. Id probably want the 7950 though if I was getting an XFX DD card. seems to make more sense, especially when overclocked to the limit.
Good cards, but far too many to choose from in the last 2 weeks. hard to know what to buy (if I was in the market).
HD6850 is the better value card IMO, its under £200 now in the UK, 6870 is too closely priced to 6950 IMO
